The Tea Ceremony Raku is basically a technique for glazing soft =
earthenware ceramics. Ameya, a Korean is said to have immigrated to =
Japan sometime in the 16th century, It is said that Tea masters were =
drawn to the tea bowls made by Ameya's widow. The thick bowls allowed =
for drinking tea and the heat was dissipated by the clay body. We all =
know the American version of tea bowls, but have changed them as we =
should, in fact, maybe we are obligated to do so.
The original glaze is said to be made from river rocks from the Kamo =
river. Potters were said to have pilfered grave yards to use the =
headstones when the particular rock was used up. The following glaze is =
one of the lowest melting glazes I have used. It was formulated by =
Richard Behrens. The rock from the Kamo river had a Lithium component =
to it (?). Behrens used lithium to lower the melt (?) The glaze is as =
follows.
Frit P 25 (Pemco) 43.6
Frit 3134 Ferro) 26.3
Lithium Carbonate 9.9
China clay (EPK) 6.3
Flint 14.0
This glaze melts at cone 016. =20
Use copper for floating tints, try everything with this glaze! Fired a =
little higher it is clear and reveals the clay body color. I have used =
this glaze on and off since 1970. =20

Subject: the absolute lowest melting glaze ever/superfast firing/glow in =
the dark
So does anyone have a recipe or know where I can get the absolute most =
lowest temperature melting glaze there ever was? like at the maximum =
i'm looking for cone 018. I have some glow in the dark pigments which =
are just not doing very well in regular raku glazes. I don't care about =
lead (although I've been told that lead will quench the glow), I'm just =
looking for LOW LOW MELTING POINT. =20
i know part of the problem with these glow in the dark pigments is that =
they have to be really fast fired. but i'm afraid of cracking =
everything. does anyone have any experience with superfast firing? I =
had thought that it was done only in industry with very meticulous =
firing curves that slow down for a few minutes around critical =
temperatures (quartz inversion, cristobalite inversion, etc). =20
anyone?
